previous 2.5.64 seemed also had #xnsub well working....
Hrm... I just hit the upgrade firmware button and it nabbed verison 2.6.1 .... any posted differences of this somewhere?
Well I can say one difference is #xnsub now works perfect out of the box and its cgminer 4.8.0 now =) woot
Good job!
What are your settings?
start volts:
1: .62
2: .62
3: .62
4: .62
Max Volts .661
max power:
1: 150
2: 175
3: 150
4: 175
Mining rates: 1229.41GH/s and 1237.13GH/s
fans are both set at 20%, I had them a bit lower but temps got a little higher in my mining area recently.
I've seen a few people utilizing different voltages now... I'll have to give it a try. Thanks!
Temps okay at fan speed 20?
No problems, but with all these boards and asics, YMMV so test it for yourself

I do not know my eight all have 2.5.64

is there a detailed explanation of all that meanings of values and colors of the ASIC Stats page?
what about limits of temps?
what about limits of temps?
I'm using different voltages as loop 4 always seems to run hotter than the others, so I typically run it a bit lower than the rest

2. what will happen if i add a second fan in front of the built in one without removing it?
...
It won’t cause any damage but it's not suppose to improve the cooling by much. 2. what will happen if i add a second fan in front of the built in one without removing it?

some SP20 pr0n for you:
>snip image<
got an EVGA 1600w PSU sitting at home waiting to plug in - I think I'll need another PSU of not massive wattage to get all 4 going

It has 14 PCIe plugs, right? So, you need just another PSU with at least two plugs, but i would just get EVGA 1300; this way you can downclock to ~700W/1250-1270Gh.
However, if you want to downclock, the trick would be how to downclock them with just one or two PSU.
You would have to do it one by one, bring to stable hash, then switch off and do another.
what is to the left of them-it looks interesting.
I have an EVGA 1300w plugged into 1 and a half SP20s. that pulls about 1100w. The 1600w is plugged into the 2 remaining PCI-E sockets on the 2nd one, the 4 on the 3rd and again 2 on the 4th. That pulls about 1400w from the wall. There are only 9 PCI-E sockets on the 1600w PSU
I think I'll swap out the 1300w and get another 1600w, then I can power all 4 across 2 PSUs leaving about 2-300w spare
The unit on the left is a tumble dryer !!
What speeds are you seeing? I'm running two SP20s off of a single EVGA 1300G2 and getting 2.4TH/s between them without issue
What are your settings?
losing like 3GH-5GH/day ... and never goes back up? ... unless I restart mining...
do you really care?
3-5 Gh/s per day are roughly 2-3% per day. E.g. pool luck is changing at a much higher rate or width.
Reboot every 1-2 days or try that trigger mike9 mentioned, no need to worry I think. Worry about you power rate $/kwh related to current BTC/$ if you need to worry

So, why does every day that goes by my SP20 keeps clocking itself a tad lower ... losing like 3GH-5GH/day ... and never goes back up? ... unless I restart mining...
Contact zvi @ sp tech support; I had a SP20 that did the same, and they RMA'd it for me.
It is not you; something a little odd with that unit
I dont wanna go through that hassle n downtime, Ill just manually reboot it every once in a while if thats what it takes ... or make a cron script or something... I ono
I was thinking about that, but thats a really aggressive use for that setting. I prefer to use that setting if one of the ASICs stops mining all together or a majority of them. But, Ill ponder it further ... if it ends up bothering me enough lol!

settings ?
210w limit per board, voltage start 685, limit 699, temps never hit over 105c
yeah try doing them all just a little power.
say 200 watts
.682 all four
and .691 max.
I think you are just touching a bit warm for that machine thus the small drop off.
I can move all six machines 20 gh or so by open and close of the door in the photos below.
The gear is a bit sensitive to temps.
I highly doubt its temperature related. All the time, all ASICs cept maybe 2 read 85C, 2 of them ... some of the time are between 105C ... those dont get throttled down tho, its the cooler ones that seem to .. I dont get it.
It seems like some of the voltages are getting raise and clocks are being dropped to keep under 210w, but that makes no sense... why would the volts get raised a tiny bit over the course of days, if the chips are already stable (no hw errors) ... etc...
could be the psu is dropping the 12volts just a little bit with constant 24/7/365 use.
and the sp20 is adjusting for the voltage supplied.
I still would try just a little lower on all settings.
maybe keep the watts all at 210 and drop every volt setting by .004.
The more I use the sp20's the more they remind me of gpu mining in the sense that every gpu is a tiny bit different from the same make and model. Also in the sense that tiny adjustments in volts can make a world of difference in preformance.
